I was wondering how many possibilities of private/public keys there are? If a million people for whatever reason tried to generate 5keys each in the same minute (on the same date and time) is there a high chance of collision? I believe GUID would suffer from that problem as many bits are reversed for date/time (, guid version) and isn't meant to be used in that way.
Would RSA get collisions if many were generated in the same moments? Is the amount of possible keys known? I know rsa is based on prime numbers and small numbers are to be rejected. I'm sure values above a certain amount of digits/bits are rejected because software may not be able to support those large values?
How many RSA keys before a collision? and if you tried to make many in the same moment would that give you a high chance of collision?
